Hi, welcome to solsarin site, today we want to talk about“where is the sahara desert located?”,

thank you for visiting our site.

where is the sahara desert located?

Blanketing much of the northern third of the African continent, or some 3.5 million square miles, the Sahara Desert, the largest desert in the world, extends eastward from the Atlantic Ocean some 3,000 miles to the Nile River and the Red Sea, and southward from the Atlas Mountains of Morocco and the Mediterranean shores more than 1,000 miles to the savannah called the Sahel. More than 16 times the size of France, the Sahara Desert blankets nearly all of Mauritania, Western Sahara, Algeria, Libya, Egypt and Niger; the southern half of Tunisia; and the northern parts of Mali, Chad and Sudan.

Geography

The Sahara is bordered by the Atlantic Ocean on the west, the Red Sea on the east, the Mediterranean Sea on the north and the Sahel Savannah on the south. The enormous desert spans 11 countries: Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia.

The Sahara desert has a variety of land features, but is most famous for the sand dune fields that are often depicted in movies. The dunes can reach almost 600 feet (183 meters) high but they cover only about 15 percent of the entire desert. Other topographical features include mountains, plateaus, sand- and gravel-covered plains, salt flats, basins and depressions. Mount Koussi, an extinct volcano in Chad, is the highest point in the Sahara at 11,204 feet (3,415 m), and the Qattara Depression in Egypt is the Saraha’s deepest point, at 436 feet (133 m) below sea level.

Although water is scarce across the entire region, the Sahara contains two permanent rivers (the Nile and the Niger), at least 20 seasonal lakes and huge aquifers, which are the primary sources of water in the more than 90 major desert oases. Water management authorities once feared the aquifers in the Sahara would soon dry up due to overuse, but a study published in the journal Geophysical Research Letters in 2013, discovered that the “fossil” (nonrenewable) aquifers were still being fed via rain and runoff.

How hot does it get?

The Sahara Desert is one of the most consistently hottest places on Earth. The average temperature during the summer months is between 100.4 °F (38 °C) and 114.8 °F (46 °C). In some areas the temperature can exceed 120 °F for several days in a row. The overall climate of the Sahara makes it a difficult place for any life to exist. It is hot, dry, and windy. Even though it is so hot during the day, the temperature can drop rapidly at night. Sometimes to below freezing. It rarely rains in the Sahara. Some regions can go years without seeing a drop of rain.

Landforms of the Sahara Desert

The Sahara Desert is made up of several different types of landforms including:

Dunes – Dunes are hills made of sand. Some dunes in the Sahara can reach over 500 feet tall.

Ergs – Ergs are large areas of sand. They are sometimes called sand seas.

Regs – regs are flat plains that are covered with sand and hard gravel.

Hamadas – Hamadas are hard and barren rocky plateaus.

Salt Flats – A flat area of land covered with sand, gravel, and salt.
